how to insert records using django models then run a update query -

-



hi have following model,

class members(models.model):   auto_id = models.autofield(primary_key=true)   created = models.datetimefield(auto_now_add=true)   member_name = models.charfield(max_length=25, blank=false, default='')   father_name = models.charfield(max_length=25, blank=false, default='')   wife_name = models.charfield(max_length=25, blank=false, default='')   hid = models.integerfield(blank=true)

i using django-rest serializers insert records.

in above hid number given each member may change depending upon insertion.

eg: 1,2,3...10 hid numbers given 10 members new member child of 3 number 4 , 4 should become 5 until end should update if member 4 deleted 5 should become 4 , 6 should become 5 show happen

how can implement concept django models , views?

note: know number after insertion should happen can choose person or hid
